What's there: Steelhead, salmon, trout and smallmouth bass.
Description: This is one of the longest undammed rivers in the U.S. It flows next to roads and highway in its headwaters, then 100 miles through the Frank Church Wilderness and back through a roaded section near Riggins before descending through another large roadless area then joining the Snake River.
It's best known for its fall steelhead runs, but also should have a chinook season this spring. The Salmon offers some good smallmouth bass fishing downstream from Riggins in summer. The Little Salmon near Riggins also has excellent spring steelhead fishing.
Jetboats, rafts and driftboats are commonly used on this river. The Salmon alternates between big, splashy rapids and long placid stretches interrupted by riffles and small rapids. Make sure you know which section you're on before you launch a boat.
Getting there: Take Idaho 55 and U.S. 95 to Riggins, or take Idaho 55 to Banks and the Banks to Lowman Highway to Idaho 21 and up to Stanley.
Drive time: About 3 hours.
